Like the others stated, just hunt the oaks. Here in Virginia, white oak acorns are THE #1 food for deer when dropping. When the acorns are dropping, that's where they'll be. I hunt the highest elevation points first and work to the bottoms from there.20 or so feet in elevation can mean one particular tree dropping a couple days before another. They also tend to eat there way out from the bedding areas. They eat every white oak acorn they can find, leaving the red oak acorns behind. The red oaks go when they white oaks have been depleated and devoured. All the white oak acorns in my yard get eaten within the same two week window every year, in the end of November. They certainly have a patteren to their feeding. Nothing scientific here, just my observations.
